BSB v WSB v MotoGP
British Superbikes = Full grid, exciting racing, not quite the most developed of machinery.
World Superbikes = Good spread of highly-developed machinery, great riders, but mostly happens outside my ability to attend.
MotoGP = Fantastically developed machinery, a few brilliant riders - although necessarily one less after Sepang - but not enough of a grid to make the racing worth watching. Mostly happens outside my ability to attend.
